i Letters Patent No. 98,549, dated January 4, `1870.

IMPROVEMENT IN' ME-CHANISM FOR STOPPING- THE DELIVERY-ROLLERS OF SPIN- NIN G--MALJHINES-` The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern i lBe it known that we, HENRY BOTTOMLEY and PETER GREENWOOD, of Camden, Camden county,

State of New Jersey, have invented certain Improvements in Spinning-Machinery; and we do hereby declare the following "to be' a full, clear, and Yexact description of thesame,

Our invention consists of certain mechanism, fully described -hereaften'for counteracting the momentum of the delivery-rollers of spinning-machines, after they are thrown outof gear, thereby insuring the making `of more uniform threads than can -be produced when Ythe delivery-rollers are uncontrolled.

In' order to enable others skilled in the art to make and use our invention, we will now proceed to describe its construction and operation, reference being had to the accompanying drawing, whichibrms a part of this specification, and inwhich- Figure ,1`is aplan view of our mechanism for controlling the ropihg in `a spinning-machine;

Figure?, the same, with some of the parts in a different position; r

Figure 3, a vertical section, on the line 1-2, fig.

Figure 4, a vertical section, on the line 3-4, iig.

Figure 5, a vertical section, on the line 5-6, lig. and w' Figure G, a diagram, illustrating ourinvention.

Similar letters referto similar parts throughout the several views.

A and A are two spindles, to each end of which are connected the delivery-rollers of a spinning-machine, that is, the rollers a a, shown .in the diagram, fig. 6, on andV between which rest the cylindrical weights or upper roller b, and between the latter and the lower rollers passes the roping to the spindles on the jack. v

It should he understood that the mechanism which p -we are about to -describe is situated midway, or thereabout, between the opposite ends of the jack, the permanent parts of the mechanism being secured to the frame of what is known as the driving-head of the spinning-machine.

` To the,4 spindle A is 'secured a clutch, c, adapted to a similar clutch, c', which is arranged to slide and turn freely, independent of the said spindle.

A` level', B, is hung toa permanent part of the frame, and the bent arm d, iig. 3, of this lever, passes -over and beneath the clutch c', a pin on the extreme end of this arm entering a groove in the said clutch.

An arm is secured to the clutch c', and this arm passes through a slot in the lever B, the upper end of the arlu being connected to a permanent pin, f, by

a spiral or other suitable spring, 7i, the tendency of which is to maintain the arm c in the positonshown in `fig. 3.

The other arm of the lever B is forked at the end,

so as to embrace lbut not impede the movements of a shaft, G, which turns in` a bearing, li', ou the frame of a machine, and which has a bevel-wheel, t', gearing into a similar bevel-wheel,- i, on the spindle A'. The shaft G turns near its opposite.` end, in a bearing, j, secured to a bar, D, arranged to slide in astationa-ry bar, E, secured to the frame-work of the machine, the outer end of the shaft having a bevel-wheel, 7G, which, under the circumstances described hereafter, gears into a similar wheel, k', on a shaft, F, which turns in the frame-work, and which may he driven by a belt orotherwse from the driving-shaft of the machine.

0n the shaft C is a worm, G, adapted to the teeth of a worm-wheel, H, which is arranged to turn freely on a stationary spindle, I, and from the under side of this wheel project two pins, an, one of which, under the circumstances described' hereafter, comes in contact with and operates the trigger n, the latter, when undisturbed, being maintained by a spring, 1J, in the position shown in iig. 1, where it serves to maintain the sliding bar D in the position shown in iig'. l, and the bevel-wheel k in gearwitlrthebevel-wheel It, until by the rotation of the wheel H, the trigger is actuated and caused to release the sliding bar D, which by a spring, q, moves the sliding bar in the direction of the arrow, iig. 4, and the bevel-wheel out of gear with the bevel-wheel la.

The mechanism which we have last described is common to other spinning-nnichines; a more minute description, therefore, will he unnecessary.

As the carriage, on which are the numerous spindles, approaches the limit of its inward movement, it is caused to so move the shaft C, as in other spinning-machines, that when the carriage reaches its destination, the wheel 'k is in gear with the wheel 7c', and consequently the spindles A and A are put in motion, for it should be here understood that the spindle A communicates with the spindle A.

rlhe rollers connected to the spindles A A at once commence to deliver -the ropings to the spindles, and

. the carriage commences its outward movement.

After the proper amount of roping has been delivered, the -pin mf, on the wheel H, operates the trigger n, and consequently the shaft G is so moved that its wheel le is out of gear with the wheelrk, and consequently the motion of the said shaft C ceases, or rather should instantly cease, for the momentum acquired by the delivery-rollers induces them-to continue their movement after the shaft C is thrown out of gear, and it is to counteract this momentum which is the special object of our invention.

Vhcu the shaft Gis moved out of gear, the-lever B is so operated that it will move the clutch c into gear with the clutch c. This, however, does not instantly stop the further rotation ot' the delivery-rollspring-rod e, traversing the slot in the arm d of the `lever B; asl soon as the arm reaches the end of the slot, however, takes place. l

After this stoppage the carriage continues its outward movement and returns, preparatory to a repetition of the above-described movements.

It will be seen, without further description, that by the above-described mechanism, the delivery-rollers are etectually controlled as regards the stoppage at the proper time, the result of this being the making the stoppage of the delivery-rollers of a more uniform thread than can be produced by the aid of uncontrolled delivery-rollers.

fe claim as our invention and desire to secure by Letters Patent- The combination ofthe clutch c, on the spindle A, the clutch c', spring-rod e, or its equivalent, and the lever B, arranged ,for operating the said clutch c',

and controlled by the shaft C, all substantially as ani for the purpose herein set; forth.

In testimony whereof, we have signed our names to this specification, in the presence ot' two subscribing witnesses.

HENRY BOTTOMLEY. PETER GREENWOOD.
